Pointer to a Consumer-allocated structure that the Provider fills with RMR
parameters.

.SH DESCRIPTION
.sp
.LP
The \fBdat_rmr_query()\fR function provides RMR parameters to the Consumer. The
Consumer passes in a pointer to the Consumer-allocated structures for RMR
parameters that the Provider fills.
.sp
.LP
The \fIrmr_param_mask\fR parameter allows Consumers to specify which parameters
to query. The Provider returns values for \fIrmr_param_mask\fR requested
parameters. The Provider can return values for any other parameters.
.sp
.LP
Not all parameters can have a value at all times. For example,
\fIlmr_handle\fR, \fItarget_address\fR, \fIsegment_length\fR,
\fImem_privileges\fR, and \fIrmr_context\fR are not defined for an unbound RMR.
.SH RETURN VALUES

.RS 25n
The operation was successful.
